Leading reed relay products supported by distributor partner ‘dedicated to excellence and customer satisfaction
Pickering Electronics, the reed relay company which has pioneered miniaturization and high performance for over 50 years, has extended its distributor partnership agreement with Wiselink to covering the Philippines. Wiselink already represents Pickering in Singapore, Malaysia and Thailand, and has recently opened a new office in Santo Tomas, just outside Manila.
Wiselink places strong emphasis on delivering the best to its customers. The company acts as a supply channel partner for over 35 suppliers and more than 2,500 OEM and CEM customers in various industries. Comments Pickering CEO Keith Moore: “Wiselink is a proactive partner for us in this important region, dedicated to excellence and customer satisfaction.”
Pickering is known for its innovation in reed relays which use instrumentation-grade reed switches with vacuum-sputtered ruthenium plating to ensure stable, long life up to 5×109 operations. Formerless coil construction and SoftCenter™ technology also help to increase reliability and robustness, while the use of Mu-metal magnetic screening (either external or internal), enables ultra-high PCB side-by-side packing densities with minimal magnetic interaction, saving significant cost and space. Also, Pickering’s reed relays are 100% tested for all operating parameters including dynamic contact wave-shape analysis with full data scrutiny to maintain consistency.

Minimum 1500V stand-off; mini SIL/SIP packaging
Pickering Electronics, the reed relay company which has pioneered miniaturization and high performance for over 50 years, has launched industry’s smallest high voltage relay. Housed in the miniture SIL/SIP package, new Series 131 reed relays have a footprint of just 12.5mm x 3.7mm and a height of 6.6mm and deliver a minimum stand-off of 1500V.
Featuring a choice of 3, 5 or 12 volt coils, with optional internal diode, Series 131 reed relays are available in the 1 Form A (energize to make) SPST N.O. configuration, and can switch up to 0.7 amps, 10 watts. Devices are ideal for cable testers, mixed signal/semiconductor testers, backplane testers, high voltage instrumentation, in-circuit test equipment or other HV applications.
Commented Keith Moore, CEO, Pickering Electronics: “Pickering Series 131 miniature SIL reed relays utilise vacuumed, sputtered ruthenium reed switches which have a superb low level performance, making them an excellent choice where a wide range of signals are involved. The range is based on our long-established Series 113 style of plastic package that incorporates an internal mu-metal magnetic screen to enable high packing density, and Pickering’s SoftCenter® construction which protects the reed switch.”
About Pickering Electronics
Pickering Electronics was formed over 50 years ago to design and manufacture high quality reed relays, intended principally for use in Instrumentation and Test equipment. Today, Pickering’s Single-in-Line (SIL/SIP) range is by far the most developed in the relay industry with devices 25% the size of many competitors. These small SIL/SIP reed relays are sold in high volumes to large ATE and Semiconductor companies throughout the world.
Pickering Electronics is part of the privately-owned Pickering Group of companies; made up of three electronics manufacturers, including Pickering Interfaces who design and manufacture modular signal switching and simulation products, and Pickering Connect who design and manufacture cables and connectors.
The Pickering 100 and 101 Series are a complete range of Single-in- Line (SIL) reed relays featuring low thermal EMF and primarily intended for direct drive from CMOS logic IC’s. The 100 series can be driven directly from 4000B CMOS or NMOS logic or similar low current sources, in addition, the mercury wetted relays in the range may be driven directly from TTL logic. The 101 series is designed to be driven direct with 5V 74HC or 74HCT logic without the need for additional drivers, this can help save valuable board space.
Pickering employ many years of know-how and experience in the design and construction of their reed relays, features such as formerless coil construction allow the coil to be wound directly onto the glass envelope containing the reed switch, this maximises magnetic efficiency and allows the use of less sensitive reed switches resulting in optimal switching action and extended lifetime at operational extremes. Other design innovations include Pickering’s SoftCentre™ technology which provides maximum cushioned protection of the reed switch, minimising internal lifetime stresses and extending the working life and contact stability. Competitors’ rigid hard moulded construction results in significant stresses to the glass reed switch which can cause the switch blades to deflect or misalign leading to changes in the operating characteristics and long-term reliability of the reed switch.
Click below for an Introduction to how Pickering Reed Relays are constructed
The 100 series are housed in a SIL package measuring just 24.1mm length by 10.2mm width, the height of the package is 12.7mm for 1 Form A (SPNO) and 1 Form C (SPCO) and 15.2mm for 1 Form B (SPNC) and 2 Form A (DPNO) contact configurations. The 101 series are housed in an even more compact SIL package measuring just 20.1mm length by 7.4mm width, the height of the package is 9.4mm for 1 Form A (SPNO) and 1 Form C (SPCO) and 12.5mm for 1 Form B (SPNC) and 2 Form A (DPNO) contact configurations. Both types are available with dry and mercury wetted switches in a range of configurations and coil voltages. The reed switches in the 2 Form A (DPNO) version are vertically stacked so the relay requires the same board area as the 1 Form A (SPNO) type.
Thermal EMF is a phenomenon whereby a very small voltage, typically in the microvolt range (μV), can be produced due to temperature variations in the contacts of a reed relay. The 100 and 101 series reed relays have internal thermal EMF levels as low as 1 microvolt (μV) for single pole types or even lower for two pole types used for differential switching, where there can be some cancellation of the thermal EMF voltages from the two switches. They feature internal mu-metal magnetic screening to avoid the effects of magnetic interaction between relays this allows very close stacking of the relays on the PCB, in the case of the 101 series these can be stacked on a 0.3 inch (7.6mm) pitch.
Dense reed relay stacking possible saving valuable PCB space
Both the 100 and the 101 series are suited to applications where conservation of current is important, for example, battery powered equipment. Their low coil power requirements and low thermal EMF figures also make them ideal for data acquisition and thermocouple switching applications.
